RAILWAY-RAIL JOINT.

SPECIFICATION forming part of Letters Patent No. 280,654, dated July 3,1883.

Application filed December 6, 1882. (N0 model.)

To all whom it may concern Be it known that I,,RIGHARD P. MORGAN, Jr., acitizen of the United States, residing at Dwight, in the county ofLivingston and State of Illinois, have invented certain new and useful.Improvements in Railway-Rail J oints; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, referencebeing had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form apart ofthis specification.

My invention consists in placing underneath the joints of the rails ofrailway-tracks what, by way of designation, I call a sub-rail, andsecuring the same to the track-rai1s by a series of clamps and keys ornuts, so that the trackrails and the sub-rail may be firmly held orclamped together, and both may be supported by the cross-ties, ashereinafter described.

The accompanying drawings are referred to as a part of thisspecification.

Figure 1 shows a longitudinal view'of the track-rails, the sub-rail, andthe ends of the ties supporting the same, and also the fasten ings whichhold together the track-rails and the sub-rail. Fig. 2 is across-section of the track-rail, sub-rail, and clamp, and exhibits therabbet in the end of the cross-tie, where the base of the sub-railrests. Fig. 3 represents a perspective view of the key which may be usedto fasten the clamps in place.

The letters on the different figures refer to the same parts.

(t represents the ordinary rails of a railway, which I have designatedas the track-rails.

I) represents the sub rail, the middle of which is placed under thejoint of the trackrails.

0 represents the clamps which are used to fasten together thetrack-rails and the sub-rail.

(2 represents the cross-ties, with the rabbet in the end of each of suchdepth that the ties support both the sub-rail and the track-rails.

6 represents a lip rolled on the outer edge of the top of the sub-rail,so that the foot of the track-rails may be held in alignment and thetrack prevented from spreading.

f represents the key-holes in the ends of the clamps c, in case theclamps are secured by keys instead of nuts.

9- represents the wedge-shaped key which is used to secure the clamps inplace.

i shows the form of the interior of the clamp, so made that its innersurfaces correspond to and rest fairly in contact with the foot of thetrack-rail and the head of the sub-rail.

Zin Fig. 2 shows the rabbet in the cross-ties.

Two or more holes or openings should be made in the sub-rail,corresponding with simi lar holes or openings in the trackiails, for thereception of the ends of the clamps, as shown. The clamps should beformed approximately like a capital U in their exterior figure. Theinterior of the clamps should conform with the track-rails and sub-rail,so that when drawn to place they will hold those rails firmly together.The clamps may be inserted in oppo site directions, as indicated in Fig.1, or they may all be placed on either side. WVhen the key 9 is insertedin the key-hole f and driven home, it draws the clamp c and holds it incontact with the track-rails and the sub-rail and binds them firmlytogether. The subrail should be of such length as to extend from themiddle of one crosstie to the middle of the next, and of such depth thatwhen it rests on the bottom of the rabbet the track-rails should restupon the top of the sub-rail, and also on the top of the cross-tiebeyond the rabbet. This difference in distance is to provide against theeffect of the expansion and contraction of the track-rails, so that witheach change in temperature a change in the position of each clamp willtake place and maintain a uniform compressive strain binding thetrackrails and sub-rail together, and is computed to be applied totrack-rails of thirty feet in length. If longer or shorter track-railsare used, these distances should be varied accordingly.

The material of which the sub-rail, clamps, and keys are made may beeither iron or steel.
